使用最新Discord JS开发斜杠命令机器人遇401未授权错误

我正在用最新版Discord JS开发带斜杠命令的Discord机器人，但每次运行都会返回Discord API错误：401: Unauthorized - Can't put application commands with REST。

我试过仅使用应用命令模块（只需要CLIENT_ID，不需要同时提供CLIENT_ID和GUILD_ID，和applicationGuildCommand不同），但问题依然存在。

机器人代码 #

import { config } from 'dotenv';
import {
    ActionRowBuilder,
    Client,
    GatewayIntentBits,
    InteractionType,
    ModalBuilder,
    Routes,
    // SelectMenuBuislder,
    TextInputBuilder,
    TextInputStyle,
} from 'discord.js';
import { REST } from '@discordjs/rest';
import pingCommand from './commands/ping.js'

config();

const TOKEN = process.env.BOT_TOKEN
const CLIENT_ID = process.env.CLIENT_ID;
const GUILD_ID = process.env.GUILD_ID;

const client = new Client({
    intents: [
        GatewayIntentBits.Guilds,
        GatewayIntentBits.GuildMessages,
        GatewayIntentBits.MessageContent,
    ],
});

const rest = new REST({ version: '10' }).setToken(TOKEN);

client.on('ready', () => console.log(`${client.user.tag} has logged in!`));


client.on('interactionCreate', (interaction) => {
    if (interaction.isChatInputCommand()) {
        console.log('Chat Command');
        if (interaction.commandName === 'ping') {
            interaction.reply("Pong")
        }
    }
});

async function main() {
    const commands = [
        pingCommand
    ];
    try {
        console.log('Started refreshing application (/) commands.');
        await rest.put(Routes.applicationCommands(CLIENT_ID), {
            body: commands,
        });
        client.login(TOKEN);
    } catch (err) {
        console.log(err);
    }
}

main();

测试用ping命令代码 #

import { SlashCommandBuilder } from '@discordjs/builders';

const pingCommand = new SlashCommandBuilder()
  .setName('ping')
  .setDescription('ping')
  .addRoleOption((option) =>
    option
      .setName('eh')
      .setDescription("huh")
      .setRequired(false)
  );

export default pingCommand.toJSON();

解决建议 #

• 检查BOT_TOKEN准确性：确认.env文件中的机器人令牌无拼写错误、无多余空格，且对应机器人账号已勾选applications.commands权限范围（在Discord开发者平台的机器人页面设置）。
• 验证CLIENT_ID正确性：确保.env中的客户端ID是Discord开发者平台对应应用的ID，而非服务器ID或其他无关ID。
• 重新生成令牌：若之前生成令牌时未勾选applications.commands授权范围，需重新生成包含该权限的令牌。
• 调整命令注册时机：将命令注册逻辑放在客户端登录成功后执行，避免REST请求先于登录发送：

async function main() {
    try {
        await client.login(TOKEN);
        console.log('Started refreshing application (/) commands.');
        const commands = [pingCommand];
        await rest.put(Routes.applicationCommands(CLIENT_ID), { body: commands });
        console.log('Successfully reloaded application (/) commands.');
    } catch (err) {
        console.log(err);
    }
}
